Don't stop till you get enough!

A few vs Few

Before I start you should know that this topic could follow the any vs some talk we've had, mmmkay? Now, let's get down to business!

Grammarwise, they're both correct. A diferença está na mensagem que queremos passar.

Se eu digo I have a few friends meus amigos não são numerosos, mas eu não me importo com isso. Qualidade x quantidade, blá-blá-blá!

Agora, se minha frase for I have few friends, bom, mimimi! Eu sou muito solitário, quero mais amiguinhos no meu Orkut!

Now, seriously, a few has a positive conotation. It's not much, but it's enough. And the opposite is true for few.

BTW (by the way, ou à propósito), same holds true for little or a little.
